'00 Boxter Oil Separator

[santambrogio]

I'm told by the local meachnic that the '00 boxster needs a new oil sepator bellow, $650 thank you very much.

The car is inherited from a relative, my first P car and I am jut not familiar with it.

Afetr some quick reserch I undersatnd that the oil separator deareated the oil returnig to the dry supm from each head? Right. wrong? And there must be 2 then?

I do all mainteance and minor repair on the cages and the bikes are the bellows something I can do?

Thanks

Only has one seperator-and the "bellows" attach bettween seperator and block. The rubber bellows crack over
time and create a vacuum leak, performance problems and
eventually "check engine light". It can be tricky to replace,
thus the price to replace. I'd have it fixed if I were you. Mike

Thanks and you are right I've got a cd of the manual and indeed there is a bellow that connects the separator to the top right rear of the crankcase. Can this vacum leak affect amount of oil that is evaquated from the crankcase? I'm getting a full oil level reading on the gage and the dip stick if the car has sat overnight and a low reading when the car is warm at a brief stop.

No not really. however it could leak a small amout. You should
always wait 15-20 minutes after shutdown to get an accurate
oil level reading(thats what the timer on the dash oil level
indicator is for). Just how low is "low"? Mike

After driving 1 hr. stop the car wait 15 min. tha oil level gage is 1 bar above the last bar. If the car sat overnight , wait for the oil level gage to finsh the wait cycle the oil level is 2 - 3 bars from the top.

Wich is the correct level the cold reading on the morning when all the oil is drained back into the 'integral dry sum' or the hot reading when the gage is done cycling after a warm motor, the manual implies its both.

The "normal operating range" is anywhere within the hash
marks to the right of the bar scale(equall to a differance of about one quart). However ideally your "overnight" reading should be to the top bar of the operating
range. Your "15 min. reading" should be between that and the halfway reading. So your oil level is fine ,and you really don't have to add any till the level drops to the lower end of the
scale. Mike

So then we can assume that the car has enough oil according to the stick and the timed gage.

Now the *sad* part why after about 1hr of driving the oil pressure light comes on at idle and there is a squealing sound similar to a belt slipping.

The stealer diagnosis was that the oil separator bellow was leaking, and that the oil was low. Could it be that the leak at the bellow is causing the oil suction pumps not get oil back to the oil tank resulting in intermittent oil flow? The light does come on while braking to a stop.

As for the squealing sound it could be a belt or it could be the extenal oil separator?

Saturday it's off with the motor top cover to see if there is a leak at the bellow and i'll take a look below the car as well.
